Age and paleoecological significance of an early postglacial fossil assemblage near Marathon, Ontario, Canada
Organic materials recovered from deltaic deposits confined to the Black River Valley near Marathon, Ontario, provide information on lake-level history and local ecology for the region. Radiocarbon samples provide the first age determinations (ca. 8200 BP) for the post-Minong III – IV lake phases alo...
